Coupon

In marketing, a coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product.

Customarily, coupons are issued by manufacturers of consumer packaged goods or by retailers, to be used in retail stores as a part of sales promotions. They are often widely distributed through mail, coupon envelopes, magazines, newspapers, the Internet (social media, email newsletter), directly from the retailer, and mobile devices such as cell phones.

The New York Times reported "more than 900 manufacturers' coupons were distributed" per household, and that "the United States Department of Agriculture estimates that four families in five use coupons. "Only about 4 percent" of coupons received were redeemed. Coupons can be targeted selectively to regional markets in which price competition is great.

Most coupons have an expiration date, although American military commissaries overseas honor manufacturers' coupons for up to six months past the expiration date.

Coca-Cola's 1888-issued "free glass of" is the earliest documented coupon. Coupons were mailed to potential customers and placed in magazines. It is estimated that between 1894 and 1913 one in nine Americans had received a free Coca-Cola, for a total of 8,500,000 free drinks. By 1895, Coke was served in every state in the United States.

Types and uses
Coupons offer different types of values, such as discounts, free shipping, buy-one get-one, trade-in for redemption, first-time customer coupons, free trial offer, launch offers, festival offers, and free giveaways.

Grocery coupons

Some grocery stores regularly double or even triple the value of coupons to bring customers into their stores. Periodic special events double or triple coupon values on certain days or weeks.

Conveyance
Coupons exist in more than one form, and are acquired by customers in a variety of ways.

Paper
Historically, verifying the discount offered has been via presenting coupons clipped from newspapers or received in the mail. Some retailers and companies use verification methods such as unique barcodes, coupon ID numbers, holographic seals, and watermarked paper as protection from unauthorized copying or use. Other than newspapers, there are also coupon book publishers and retailers who compile vouchers and coupons into books, either for sale or free.

Electronic

Taxation
Depending on the jurisdiction, coupons may or may not reduce any sales tax to be paid by the consumer. The most consumer-friendly tax situation taxes the actual price paid, including when the store does double and triple coupon reductions.

The above applies when the retailer is the source of the coupon, since the product is offered at the post-coupon price. In jurisdictions seeking to tax more, if the coupon is issued by the manufacturer, the original price is still paid but some of the price is covered by the manufacturer instead of the consumer and the full price remains taxable.

Trading
Coupon manufacturers may or may not place restrictions on coupons limiting their transferability to ensure the coupons stay within the targeted market. Since such restrictions are not universal and are difficult and/or costly to enforce, limited coupon trading is tolerated in the industry. Organized coupon exchange clubs are commonly found in regions where coupons are distributed. Often coupons are available for purchase at some online sites, but since most coupons are not allowed to be sold, the fee is considered to be for the time and effort put into cutting out the coupons.
